Question

in the right Triangles 1 divided by 4000 length of the longest is equal of 3 / 5 of the shortest length what is the ratio of the length of the importance of the length of the shorter leg

Answer 1

in a right triangle the longest side is called hypotenuse you typed wrong as length of importance
let length of shortest side = x units
length of the longest side = y units
given 1/4000 of longest side =3/5 th of shortest side

1/4000 * y = 3/5 * x

y/x = 3/5 * 4000/1

therefore
ratio = y/x = hypotenuse/shortest side = 2400/1 = 2400:1
